Bravo drive wont go on, yoke is tight on new engine coupler

[Frankiea87]

hey guys i have a 454 with a bravo drive, previously i had an alpha and converted over to bravo changing out everything, anyways i baught the new engine coupler and the drive wont go on, i aligned the motor with the alignment tool and that fits perfectly smooth and good spline marks, then i took the yoke off the drive and that wont go into the coupler.(gimble bearing is seated all the way in) i then banged the yoke and it goes into the coupler all the way and taking it off i pulled it out with one easy tug with ratchet strap hooked to it. anyways i pulled the motor back out to test out the fit of the yoke into the coupler and it fits very snug, ive removed and installed many other drives in my past but never with a new engine coupler, could this be just because its new and not broken in yet? or any other possible problems? i would haveto bang the drive on if this is normal?
